Day 6 and no weight loss...HELP

I'm finishing day 6 of my first cleanse following Master-Cleanse and I've only lost 2 pounds! I'm following the diet to the letter........SWF in am, 6 glasses of lemonade, and laxtive in pm, plus lots of water during the day. Has anyone ever experienced this? Will the weight drop off all at once? Should I be doing something else? I'm female, 42, and about 70 pounds over weight, so it's not like my body doesn't have enough to get rid of. Any feedback, help, support will be greatly appreciated. Tweet
